HENRY MYERS, OF ALTON, ILLINOIS.

DOOR-HANGER.

SPECIFICATION forming part of Letters Patent No. 327,450, dated September 29, 1885.

Application filed July 16, 1885. (No model.)

To all whom, t may concern,.-

Be it known that I, HENRY MYERS, a citizen of the United States, residing at Alton, in the county of Madison and State of Illinois, haveinvented certain new and useful Improvements in Sliding Doors, of which the following is a full, clear, and exactdescription, reference being had to the accompanying draw ings, forming part of this speciiication, in which- Figure l represents a side elevation of a sliding door and showing my improvements applied thereto. Fig. 2 is a sectional view of the upper part of the door and showing the connecting-bar which engages the shaft of the rollers. Fig. 3 represents details of construction to be hereinafter referred to.

My invention relates to sliding doors; and it consists, essentially, in a friction roller mounted on the door and provided with a coiled spring, which automatically returns the door to its normal position after it has been opened, or which will open the door upon releasing a suitable catch.

lt further consists in the peculiar construction and combination of devices which I shall hereinafter fully describe, and point out in the claims.

To enable others skilled in the art to make and use my invention, Iwillnow proceed to describe the manner in `which I have carried it out.

In the said drawings, A represents a suitable framein which the sliding door B works, and this frame maybe constructed to receive either single or double doors,as desired.

The door B has projecting from its upper surface the hangers a a', which are slotted at b, to receive a connectingbar, C, which separates each pair of rollers from the other. The ends of the connecting-bar Cengage the slots in the hangers, and the bar is notched at d d for the reception of the shafts D D of the hanged rollers E E, F, and G. These shafts engage the notched portions of the connectingbar, so that when the door is opened or closed the rollers which support the door are caused to travel backward or forward upon their tracks.

The rollers F and G are loosely mounted upon their shafts D', and the periphery of the roller G is serrated or roughened at e, so that the roller will more readily engage the track. The roller G is also provided with a chamber, g, in which is placed a coiled spring, II, one end of said spring being secured to the roller, while the opposite end engages a pin, h, on the end of a crank-arm, J, secured on the shaft.

-diately uncoils and automatically causes the door to resume its normal position.

If it be desired to have the door close after rithas been opened, the same devices are used, the spring being wound or coiled by the door being opened; but the door automaticallyr closes itself upou being released.

Having thus described myinvention, WhatI claim as new, and desire to secure by Letters Patent, is

l. The combination, with a sliding door and its hangers, of the rollers E, F, and G, the latter having a serrated or roughened surface, whereby it is held in frictional contact with its track, and provided with a coiled spring which automatically returns the door to its normal position when released, substantially as herein described.

2. As an improvement in sliding doors, a roller having au internally-placed spring,and provided with au arm having a pin which engages and coils the spring by the revolution of the rollers, substantially as herein described.
